yoke, which are preferably of like construc tion, is provided 'with fa rect-angular Irecess 38 near its rear end and in which is ,adapted-- to be received one side of the substantially rectangular spring casing 29. Each'meinberv E has its forward portion tapered as indicated at 39v and provided lwith 'a slot A48, as hereinbefore described.' The yoke members fit over the spring casing 29, and lclear the cylinder or shell 28. The members are guided and supported in operative position bv the casing 29 and a detachable saddle plate 40 supports the central strap D and the shock absorbing mechanism therewitliin, a flanged spacing and Awear plate 41 being interposed between the saddle plate andthe central strap D, and held .in positionby the downwardly projecting flanges thereof. The frontend portions of the members 'E are adapted to Vhave sliding engagement between the guide plates 37 andthe complexguide# plate 33,' and the rear end portions thereof are disposed betweemthe innersides of the front ends ofthe 'walls'12'of the'casting A and the front end portion of the blockB, the outer iside' faces tliereof-l1aving'sliding engagement lwith 'the inner edgesll ofthe flanges 19. 'l

Thefcentral strap D is in the form of a yoke, having'upper and lower parallel arms 42 embracing the shock absorbing mechanism and straddling the casing 29, the arms 42 being connected at their'front endsvby a vertically extending portion 43 adapted to co-act with and abut the lrear face -of the draw-bar 34.

At the rear ends, the arms 42 are-provided with inwardly extending projections 44, thereby providing transverse shoulders 45, the projections being formed by doubling over the'ends of the arms, as clearlyl shown in Fig. 2, or in any other suitable manner. Theprojections 44 are 'slidingly received within the recesses 2 5 of the block B and the shoulders 45 are'adaptedto `co'-act with the shoulders 26 tolimit the .forward movement of the central strap vl A band 46 of rectangular outline surrounds and engages the rear end portions of the arms 42 preventing separation ofthe same and holding theI parts in assembled relation, the .recessed portion 18 of the top wall accommodating the upper part ofthe band and upperiarm 42 of the strapD. v

The entire mechanism is readily removable from between the sills, it being merely necessary todetachthesaddle plate and remove the key'35 tolowerthe s ame,the flanges 2 2 of the Afiller-" block slidingl downwardly in theY guide channels of the stop casting, the

opening lenfthe.. bottom Ot t e latter perf 1nitting--withdrawal ofthe filler? block. In placing-'thev gearfin operativeilposition between the draft sills, the assembled mecha- Inism is inserted between thesame from the bottom, the filler-,block-being passed through the openingl' and the flanges 22 engaged within the guide channels 21.

All the parts are readily removable and by employing the-tworpart yoke, I am enabled to use a key connection with the coupler and at the same time the yoke members E-E are independently longitudinally .movable to thereby accommodate'l themselvesto the movementszof 'thecoupler' when the latter is swung radiallyy asoccurs when the cars are traveling over ,curved tracks. f

The operation iszasfollows In buff the draw-baripresses;against the'strap D moving the latterfre'aiwardly `thus -actuatingfthe friction mechanism-,since the combined shell and casing 2829 is prevented lfrom rearward movement by engagement with the'front face 23 of' the @filler'rblockf-B, l.held .against vrearwardmovement by abuttingthe wall 15 of the fixed stop casting A.-..='Rearw.ard move-y ment lof.the:-strapfD=.relatively to the ller block Bispermitted by the en'ds of the strap sliding in the recesses 25 of theblock;

Upon draft; the strap D is prevented from movement by the shoulders-45- on the arms 42 engagingwith fthe? shoulders 26 of the filler block Bgthe block B .in'turn vbeing held in fixed position: byi'theflanges22 thereof engaging-'the abutments' 20 on'. the stop casting, so that as the draw-bar moves forwardly 'carrying the two part yoke E-E therewith, the friction shell and casing 28-29 slides forwardly-relatively to the wedge' and shoes of the friction mechanism, thereby. absorbing the shock as will be understood.

I have herein shown and described-what I now consider the preferred mannergofcarrying lout the invention, b'ut the' same is merely illustrative, and I contemplate all changes and modifications thatcome within the scope 'ofLthe claims appended hereto.`
